Projection-Enhanced Disk Breaks: Evidence from Deep Photometric Decomposition
Sergey S. Savchenko, Ilia V. Chugunov, Alexander A. Marchuk +5
Radial brightness profiles of disk galaxies often exhibit so-called breaks -- locations where their exponential-scale length abruptly changes. Some galaxies have downbending (Type…
The Edge-on Galaxies in the DESI survey (EGIDE): sample building and photometry
Alexander A. Marchuk, Sergey S. Savchenko, Dmitry I. Makarov +7
We present the EGIDE (The Edge-on Galaxies in the DESI survey) project - a catalogue of 149,215 edge-on galaxy candidates created using the data of the DESI Legacy Imaging Survey D…
A New Cartwheel-like Collisional Ring Galaxy
Vladimir P. Reshetnikov, Sergey S. Savchenko, Alexander A. Marchuk +5
We report the discovery of a new Cartwheel-type collisional ring galaxy, PGC\,1112751, which we named ``Eridanus Wheel'' (EW). Such systems result from head-on collisions between g…
Clumps in spiral galaxies at : Disentangling two spatial modes of star formation
Ilia V. Chugunov, Alexander A. Marchuk
At high redshifts, star formation in galaxies is more often concentrated in clumps than in spiral arms. Although clumps are actively studied, it is rarely done considering spiral a…
Galactic disc warps from to modern epoch: ruling out observational effects
Ilia V. Chugunov, Vladimir P. Reshetnikov, Alexander A. Marchuk
A significant fraction of galaxies show warps in their discs, usually noticeable at its periphery. The exact origin of this phenomenon is not fully established, although multiple w…
Galactic warps: from cosmic noon to the current epoch
Vladimir P. Reshetnikov, Ilia V. Chugunov, Alexander A. Marchuk +6
Approximately half of all disc galaxies exhibit appreciable warps in both their stellar and HI discs. The typical warp amplitude is small (a few degrees), and only becomes noticeab…
